Table S1:
Area of glaciers [km2] in Vorarlberg in the third national glacier inventory (GI3), 2017, 2020, 2022, 2023 and the number of individual fragments per glacier in each year
number: sequential numbering corresponding to Fig 1. 
id: Inventory ID number. 
yearGI3: year corresponding to G3 area for each glacier
2017, 2020, 2022, 2023: Glacier area in the given year [km2]
year_u: area uncertainty [km2]
year_f: number of fragments per glacier in the given year


Table S2: 
Area change [km2] for different time steps.
Uncertainties in area change computes as the root-sum of the squares of the two corresponding glacier areas.

Table S3:
Relative area change rates [percentage relative to the older outline] for different time steps.


Table S4:
Overview of elevation change, volume change, and geodetic mass balance for 2017-2023
dV: Volume change in m3
dh: mean elevation change per glacier in m
dh_a: elevation change rate in m/a
geoMB: mean geodetic mass balance [m w.e. /a] for 2017-2023. Computed from dV, the average area, and a density assumption of 850 kg/m3
geoMB_u: uncertainty of mean geodetic mass balance [m], propagated from the uncertainties of the components.
2017: glacier area in 2017 [km2]
2023: glacier area in 2023 [km2]
elevation: mean glacier elevation in 2017 [m a.s.l.]


Table S5:
Number of fragments larger than 0.01km2, area and elevation statistics for categories of glacial fragments in 2023. All area values are given in km2. All elevation statistics refer to mean glacier elevation (same data as in Fig. 4f, i.e., statistics for the sample of mean feature elevation values) and are given in m.a.s.l. Categories: All, with and without visible crevasses, with some debris cover, with no debris cover.
